A method for dequantizing quantized data is provided, where the quantized data includes multiple encoded versions of source data. An initial encoding of the source data is received, where the initial encoding includes a sequence of quantized symbols. At least one additional encoding of the source data is received, where the at least one additional encoding includes a sequence of quantized symbols. The initial encoding and the at least one additional encoding are independently encoded. The initial encoding and the at least one additional encoding are aligned. A quantization interval of a symbol in the initial encoding is determined. A quantization interval of a corresponding symbol in the at least one additional encoding is determined. An intersection of the quantization intervals of the symbol in the initial encoding and the corresponding symbol in at least one additional encoding is determined. Based on the intersection, a dequantized symbol is generated.
